Wideband H-plane dielectric horn antenna

Juan Ramon Mosig, Maria Garcia Vigueras, Lei Wang

By flaring a dielectric waveguide in the H-plane, an H-plane dielectric horn is formed, which could be directly excited by an SIW feed. However, matching and radiation performances are poor due to the thinness of the substrate. To improve these performance ...

Enhancing the Performances of H-plane SIW Horn Antennas

Juan Ramon Mosig, Benjamin Fuchs, Benjamin Fuchs, Marc Esquius Morote

The performances of SIW horns antennas diminish significantly when the substrate thickness is much smaller than the free space wavelength lambda(0). Specifically, the mismatch between the antenna aperture and the air yields to unwanted back radiation and p ...
